Green HPC Podcast Episode 6: Green technologies of the future


Throughout this series we’ve talked about the motivations, goals, and approaches that leading edge supercomputing centers are taking today to improve the energy efficiency of the work they do. But if we are to really transform our approach to energy use in the context of supercomputing, we will need a dramatically expanded toolbox of techniques and technologies. In this episode we talk with the companies and centers at the forefront of research that will create the green technologies of the future.

There is a lot of activity — and a lot of hype! — today around the ways in which vendors and large supercomputing centers are trying to reduce their power usage while still getting useful work done. But there is only so much you can do adapting today’s technology, and to truly transform our approach to energy use in HPC we will need new technologies for operations and instrumentation, control system software, operating systems, job schedulers, computational algorithms, chip design, networking, and in many other areas.

In this episode we talk with companies and supercomputing centers at the forefront of thinking today about the new technologies we’ll need tomorrow. In our conversations we touch on the full spectrum of green technologies, from “bits to buildings” as Horst Simon says. On the buildings side of the spectrum we talk with our guests about local power generation and integrated approaches to work scheduling that incorporate knowledge and power rates and datacenter hot spots, integrated monitoring, and allocating user time in kW-hours instead of CPU hours. On the bits side we talk about evolutions of today’s processor architecture, the likelihood of a return to custom processors for HPC, and technologies for the rest of the computer that will provide us both the opportunity — and the challenge — to completely rethink the way we structure algorithms.

This is the final episode of the Green HPC podcast series, and in it we look at what the future may hold.

Pat Tiernan, Climate Savers Computing Initiative

Pat TiernanStarted by Google and Intel in 2007, the Climate Savers Computing Initiative is a nonprofit group of eco-conscious consumers, businesses and conservation organizations. The Initiative was started in the spirit of WWF’s Climate Savers program which has mobilized over a dozen companies since 1999 to cut carbon dioxide emissions, demonstrating that reducing emissions is good business.

Pat Tiernan is CSCI’s Executive Director. Before joining Climate Savers Computing, Pat Tiernan served on the Initiative’s board of directors as a representative of HP. At HP, Pat Tiernan was the vice president of Social and Environmental Responsibility, running the company’s sustainability programs. He joined HP in 1995 and has held a number of senior management positions in sales, marketing, product development/R&D and operations. Prior to joining HP, he helped launch a successful networking and software company and managed a global device business with an industrial technologies company where he developed and launched new products for automotive emissions compliance, patient monitoring and other commercial and consumer products. Pat Tiernan holds a Masters in Science from California State Polytechnic University.
